fix(latex): brace bracket-leading bullets, document escapes, pin pdftotext encoding

Three findings from the 2026-08-19 review (F9, F31, F34):

- F9: every placeholder bullet written as \item [text] let LaTeX parse
  the bracketed text as the item's optional label, rendering it clipped
  off the left page edge and absent from the PDF text layer ("Achievement"
  appeared 9 times in cv/main_example.tex and 0 times in the extraction,
  with a clean compile and green CI). Bullets are now braced as
  \item {[text]} in the example CV and in the template
  06-cover-letter-templates.md teaches, and CI's stock PDF assertions
  additionally require "Achievement" to survive pdftotext.

- F31: 05-cv-templates.md gains a "LaTeX Special Characters" section and
  06's is completed beyond \_ and \&. The load-bearing case is an
  unescaped % in a quantified achievement bullet: it starts a LaTeX
  comment and silently deletes the rest of the line from the PDF.

- F34: the documented ATS extraction commands (apply.md,
  05-cv-templates.md, CLAUDE.md) now carry -enc UTF-8. Xpdf-based
  pdftotext builds default to Latin-1 output, so a correct non-ASCII CV
  failed the replacement-character parseability check.

framework_version: 05-cv-templates.md 1.4.1 -> 1.4.2,
06-cover-letter-templates.md 1.0.1 -> 1.0.2. All three pinned by the new
tests/test_latex_guidance.py (9 tests; suite now 261).

 ### Added
 
+- **LaTeX special-character guidance for CVs** (`framework_version` 1.4.1 -> 1.4.2 in
+  `05-cv-templates.md`, 1.0.1 -> 1.0.2 in `06-cover-letter-templates.md`) - `05` gains a
+  "LaTeX Special Characters" section and `06`'s existing one is completed beyond `\_`/`\&`.
+  The load-bearing case is an unescaped `%` in a quantified achievement bullet: it starts a
+  LaTeX comment, so "cut latency by 40% and saved DKK 2M" compiles with zero errors and
+  renders as "cut latency by 40" - silent content loss in the deliverable, on exactly the
+  content the guidance steers users to write. `&` in employer names (Bang & Olufsen, H&M)
+  fails loudly at compile time and is now documented alongside. Pinned by

 - **`seen_jobs.json` entries record which mechanism produced them** - a new additive `source`

   rule tagging fallback results at collection time, and a `fallback (websearch):` line in the

 ### Fixed
 
+- **Example-CV bullets no longer swallowed as LaTeX optional labels** - every placeholder
+  bullet written as `\item [text]` (11 in `cv/main_example.tex`, 3 in
+  `06-cover-letter-templates.md`'s taught template) let LaTeX parse the bracketed text as
+  `\item`'s optional argument: the shipped example CV rendered all Professional Experience
+  bullets clipped off the left page edge, with the word "Achievement" appearing 9 times in
+  the source and 0 times in the PDF text layer - a clean compile, green CI. Bullets are now
+  braced (`\item {[text]}`), the cover-letter guide teaches the braced form, and CI's stock
+  PDF assertions additionally require `Achievement` to survive `pdftotext`. Pinned by
+  `tests/test_latex_guidance.py`.
+- **Documented ATS extraction commands pin `-enc UTF-8`** - `pdftotext -layout` without an
+  encoding flag emits Latin-1 on Xpdf builds, so every non-ASCII character in a correct CV
+  (Rambøll, Ingeniør, København) read back as a replacement character and failed the
+  parseability checklist, steering the agent to "fix" a healthy document. The commands in
+  `apply.md`, `05-cv-templates.md`, and `CLAUDE.md`'s verification checklist now carry
+  `-enc UTF-8`, which is deterministic on both poppler and Xpdf. Pinned by
+  `tests/test_latex_guidance.py`.

 - **`jobbank-search` search output now carries the `/scrape` contract's `date` field** (#342) -
   the CLI emitted `posted` (full ISO 8601) but not the cross-portal `date` key, the one Step 2
   contract field it was missing. Search results now additively emit `date` as `YYYY-MM-DD`
